Abstract
Adaptive Modulation and Coding (AMC) and power control are adopted to balance spectral efficiency and coverage facing the problem of spectrum shortage in recent years. Considering the Orthogonal Frequency Division Multiplexing (OFDM) scheme with high spectral efficiency and the Single Carrier-Frequency Domain Equalization (SC-FDE) scheme with wide coverage, this paper combines the switching of carrier schemes with AMC and power control to maximize system throughput. The proposal of hybrid carrier communication system based on Weighted-type Fractional Fourier Transform makes the integration of OFDM and SC-FDE possible, which solves the problem of smooth transition between the two schemes. This paper analyzes the relationships between coverage and spectral efficiency in the flat fading channel and gives suggestions to the user equipment of different carrier schemes. Then we have proposed the calculation strategy of power control parameters and the switching strategy of the carrier schemes and modulation and coding schemes under power control in the frequency-selective fading channel.
